LUBRICATING SIDE BEARING FOR CARS.

SPECIFICATION forming part Letters Patent No. 767,745, dated August 16,1904,

Application filed February 15, 1904-.- $erial No. 193,574- (No model.)

T all whom it 777M147] concern:

Be it known that I, GEORGE GALLowAY, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented new and useful Improvements in Lubricating Side Bearings forCars, of which the following is a specification.

This invention relates to lubricating side bearings for railway andstreet cars.

Side bearings have heretofore been made in which the lower bearingmember, which is secured to the truck-frame, is hollow and constitutes alubricant-receptacle from which the lubricant is fed upwardly to thebearing-faces 5 of the upper and lower bearing members by wicking orwaste confined in the receptacle and having portions exposed throughholes in the top of the lower bearing member. Such constructions areobjectionable principally in that the upper face of the lower bearingmember is repeatedly exposed in use and permits the wicking or waste tocollect dust and dirt, which cakes the exposed top portion of thewicking and prevents it from properly feed- 5 ing the lubricant to thebearing-faces.

The object of this invention is to provide a lubricating side bearing ofsimple and durable construction in which the bearing-faces will be keptclean and properly lubricated 3 and which will operate withoutreplenishing for long periods, and also to so construct the bearing thatin case the truck is derailed the bearing members will not interlock,thus permitting the car to be replaced without jacking up by theordinarycar-replacing switch or track.

In the accompanying drawings, Figure 1 indicates by dotted lines one endof a car and truck provided with a side bearing, shown in Like lettersof reference refer to like parts in the several figures.

' struction.

The upper bearing member B is curved horizontally concentrically withthe axis about which the truck turns and is secured to the 5 car-bottom,for instance, by bolts (not shown) passing through bolt-holes C in thehorizontal end flanges O of the bearing member. The latter is hollow andconstitutes a receptacle or reservoir for the lubricating-oil and oily7. waste ordinarily employed, which is shown at D. The upper bearingmember is provided in its bottom with one or more (preferably two)lubricant-feed openings E, which are preferably elongated and extendtransversely across the bottom of the bearing member for practically theentire width of thebearingface of the lower member, so that thelubricant is distributed over the whole of said face. The feedropeningsare surrounded by upright marginal flanges e, which extend well up intothe lubricant reservoir or chamber to prevent the lubricant from flowingout of the feedholes and wasting. The oily waste extends down into andthrough the feed-openings into 5 contact with the top face of .the lowerhearing member to wipe and lubricate the same in the movements of thelatter against the upper bearing member. When the hollow upper bearingmember is filled with lubricant 9 and waste and secured to the bottom ofthe car, the lubricant-chamber is closed to confine the waste andlubricant and prevent its escape from the reservoir or chamber. Thelubricant reservoir or chamber is of a size tocontain sufficientlubricant to properly lubricate the bearing for a long period of timeand does not have to be removed from the car to replenish the lubricantand waste except at such times as the car in its ordinary wear and tearis returned to the shops for repairs. As the lubricant-feed openings arein the bottom of the upper bearing member,

the waste therein which feeds the lubricant to the bearing-faces cannotcollect and hold dirt and dust as it does when located in holes in thetop of the lower bearing member. The device therefore always properlyfeeds the lubricant and wipes and lubricates the bearing-face of thelower bearing member, while the wasting of the lubricant is prevented bythe lower bearing member, which underlies and closes the lubricant-feedopenings.

F represents afilling-opening in the side of the hollow upper bearingmember, which is closed by a screw-plug or other suitable device.

The upper bearing member is provided at its opposite ends with beveledor rounded vertical webs or ribs G, which connect the bottom portion ofthe member with the enclsecuring flanges thereof. These webs or ribsserve to strengthen the bearing member, and in the event of the truckleaving the track, and thereby throwing the lower member out frombeneath the upper bearing member, as indicated in Fig. 6, they engagethe end of the lower bearing member and, owing to their beveled orrounded edges, are enabled to ride upon the lower bearing member whenthe truck is swung back into place on the track by the ordinary carreplacing switch or track. If the upper and lower bearing members wereprovided with abrupt end faces, such replacing of the car would beimpossible,and it would have to be jacked up to permit the upper bearingmember to be returned to its place on the lower bearing member.

I claim as my invention 1. In a car side bearing the combination with alower bearing member, of an upper bearing member movable on said lowerbearing member in an arc about a center situated outside of said bearingmembers and having a lubricant-chamber provided in its bottom with oneor more feed-openings which are closed by the lower bearing member andfeed the lubricant thereto, and marginal flanges which surround saidfeed-openings and project up into said lubricant-chamber, substantiallyas set forth.

2. In a car side bearing the combination with a lower bearing memberhaving a flat bearing-face, of an upper bearing member having a flatbearing-face movable on the flat bearing-face of the lower bearingmember and havinga lubricant-chamber provided in its bottom with one ormore feed-openings for the lubricant, marginal flanges which surroundsaid feed-openings and project up into said lubricant-chamber, and aporous material in said feed-openings, substantially as set forth.

3. In a car side bearing, the combination with a lower member, of anupper member provided with a lubricant-chamber having one or morefeed-openings in its bottom for the lubricant, and inclined portions atthe ends of the bearing adapted when the upper member is displaced toride upon the lower bearing member, substantially as set forth.

4. In a car side bearing, the combination with a lower member, of anupper member provided with a lubricant-chamber having one or morefeed-openings in its bottom for the lubricant, horizontalsecuring-flanges at the ends of the bearing member, and vertical ribsconnecting the bottom of the bearing member with said securing-flangesand having inclined or beveled lower edges, substantially as set forth.

Witness my hand this 12th day of February, 1904.
